Three species of monogeneans were collected from Epinephelus morrhua, a deep-sea grouper from the external slope of the coral reef, off New Caledonia, South Pacific, and are the first parasites recorded from this fish species. Pseudorhabdosynochus morrhua n. sp. is characterised by: a sclerotised vagina with small sclerotised chambers and a short secondary canal; squamodiscs with central rows of rodlets which form closed ovals; and a scaly tegument. P. variabilis n. sp. has: a male quadriloculate organ with a characteristic structure; a sclerotised vagina in which the primary canal, secondary canal and accessory structure are very long and the different parts have various arrangements in different specimens; its squamodiscs have central rows of rodlets which form closed circles; and a smooth tegument. A prominent vaginal structure, comparable to that of P. variabilis, has been found only in P. dolicocolpos Neifar & Euzet, 2007, but the species can be distinguished by details of the vagina and other structures. A species of Haliotrema Johnson & Tiegs, 1922 (Ancyrocephalidae) is reported but not described. Specimens of each of the three species were present in similar numbers.
